Can the idle speed on a 24 valve 2nd gen cummins be adjusted? If so how? My truck idles at 740-750 rpm, I would like it to idle around 800 rpm so it don't die when shifting into drive. The truck has a Low Stall TC and it is causing the truck to die when shifted into drive. If I hold the rpm to around 800 it don't stall. Does it warm or cold. Yes, fuel pressure is there (17.5), CKP was replaced 15 months ago, IAT and MAP are new, grounds and batt connections are clean and tight, batteries are well charged, alt is putting out 13.58 volts at the batt.

Wow! That's wild to see poor fuel effect it that bad... I'm sure your going to be picky about what you put in the fuel tank from here on out...

is there any difference in power or MPG over the "winter fuel" you had in you tank? it is pretty wild

No noticeable diff in power, wasn't tracking mileage. Sorry Jim
